Source for alpha amylase sought

From: Jonathan Paul Derow <*paper.conservation*> Date: Wednesday, September 18, 2002 · paper.conservation

I am looking for a source for alpha amylase for use in removing old
starch paste from paper.  I had been getting it from Sigma (item
A6814, from Bacillus species), but their price for 1,000,000 units
has gone from $10 to more than $60 in the last few years.  Does
anyone have a less expensive alternative?
